Referring to the drawings- 1 will iirst describe the construction andoperation of the .embodiment seen'in Figs. 1 to 10 inclusive. y f

1 designat a lead pencil embodying my invention. The outer sheath orcasing of the pencil is made in sections. The body or grasping portionis formed by a tubular sheath 2 which receives at its forward end thereduced end 3 of a tubular 'section 4, which is'secured to the graspingportion 2 in any desired manner, for example, by adhesive or by having adriving t. The section 4 has an aperture 5 which is contracted at itsforward end to serve as a'guide and support for the lead or insert 6,'and at `its rear end, the aperture is of enlarged diameter as at 7, andis provided with a shoulder 8.

9 and 10 represent, respectively, the'filler sections which aresemi-cylindrical in contour. The inner faces of the ller sections aregrooved as'at 11 and 12 respectively, so that when the sections are inassembled position in the sheath, a longitudinalbore is provided toform' a guide and support for the lead 6 and to receive a follower 13j,which effects the ladvance of the lead when desired.

The filler section l10 is fixed Ywith respecttothe inner wall of thesheath in any esired manner, and at its forward end, it; is .cut

away as at14, to adapt itv to enter the aperture 7 and abut against theshoulder 8 of the sheath section 4. The section 9 is slidable within thesheath and has itsfront portion cut away at its periphery, as at 15, toadapt it to enter the aperture 7 and abut against the shoulder 8. Thecut away portions 14 and 15 form respectively the shoulders 16 land 17.

In order' to limit .the relative movement permitted between the fillersections, the sec-v tion 9 is provided at its periphery with a circulargroove 18, and the section 10 is provided with a circular groove 19.lOne of thesegrooves is wider than the other, and as illustrated, thegroove 18 is'wider thanv the groove 19, A clip 2() which consists yof asplit ring is seated in .the grooves 18 and 19. The rear end portionsofthe filler secltions are cut away at their periphery, as at 21 and 22,to form 'with the inner wall of the sheath an annular chamber 23 intowhich telescopes the tubular extension 24-of an end cap or sheathsection 25. The rear end of the filler section 9 is xed to the end cap25 in any desired manner, for example, by adhesive, but the ller section10 is not connected with such end cap,'so that when the end cap it, andthe filler section 10 remains stationary. The follower 13 is preferablyconstructed of a strip of spring metal which is bent upon itself to forma forward end 26 to contact against the rear end of the lead 6,

and with spring arms 27, which at their free ends are outwardly deectedto form the prongs or cutting members 28.

Assuming now that the parts are in assembled position and the llersections are in the position seen in Fig. 2, the operator holds thesheath 2 in one hand and grasps the end cap 25 and draws' it rearwardly,so that the filler section 9 slides over the prong 28 with which itcooperates. The other opposite prong is seated in the notch 29 andprevents rearward movement of the follower. When the end cap is nowmoved forwardly relatively to the sheath section2, the juxtaposed prong28 bites into the wall of the oove 11 forming a notch 30 and the section9, the follower 13 and the lead 6 move forwardly in unison to cause thelead tov extend a desired distance from thefront end of the pencil.

If a pencil is desired `in which the lead is refillable without takingthe pencilapart, I employ the embodiment seen in Figs. 11

to 19 inclusive, to which attention is'now p directed.

' In this embodiment, the sheath consists of a tubular section 31 andatubular cap 32 which receives the filler sections 33 and 34 respectivelywhich abut against the shoulder 35 and are groovedl to form whenassembledv section 34'l and these grooves receive a'- split ring 41which is seated in an annular recess 42 in the inner wall of the sheath31,

and this retainsthe filler sectiony 34 in fixed relation to theshea'th31 to prevent their relative longitudinal movementyyThe cap 32 instead'of being iixed to the movable vfiller section, as in Fig. 1, isslidable on it.

The movable section 33is provided with a groove 43 which is narrowerthan a groove 44 in the fixed' section 34, and these grooves recess 46in' the end cap 32. `The follower .receive a split ring 45 whichisseated in 'a -20 47 consists of a strip of spring metal bent4 uponitself to lform a lead contacting end 48, and the bowed spring arms 49and 50,

arm 49 being the longer and having its free .end bent outwardly to forma prong 51,

while the arm v50 bears against the arm 49v one of which is longer thanthe other, the

and is outwardlydeiiected to form a4 prong 52. The lead 53 1s firstinserted mto the pencilthrough the opening 38 and the follower l 497then inserted throu h such opening 38, v.the lead'and follower eingreceived in the longitudinal aperture formed by the grooved fillersections. When the .end cap 1s moved rearwardly relatively to thesheath, the `movable filler section will slide over the .pro v.51 andthe prong 52 ofthe follower willni te into the section 34. The end capis' now moved forwardly and the prong 5.1 will bite into the movablesection 33 and move with it together with the follower so that the leadwill be movedforwardly in i the sheath, as is evident. g v

It -is desirable 1n some casesv to have a pencil of the type hereindisclosed,fin'which the point of .the lead can be moved back into thesheath when the pencil is not to beused,

and' thus prevent the point of the leadfrom the Eller section `55 iswider than-the groove -60 inthe ller section.A The forward end'becoming. broken. I have vshown 'a pencil 4having 1 this feature in.thev -embodlment shown in Figs. 20-24, inclusive, to whichiguresattention is'l nowdirected. In this embodiment, I employ asheath'53 Iand anend cap154. The filler members 55 and v56 are 'bothrelatively movable with respect to the sheath 53,'as they are eachprovided withl a peripheral groove to receive a split ring 57 narrowerthan each groove and seated in a vrecess 58 in the sheath. The groove 59in of the'groove '59 is in vadvances of the forwardendof the groove 60.The 4end cap 5.4 is slidable on the filler section 56 and has av recess61 in which is seated a s lit ringn 62 ller sections.

whichis in a groove 63 in the 56 and a groove 64 in the section 55, thegroove 63 `having a desired width to provide for limited relativemovement of the The follower 65 is similar to Vthat seen in Fig. 2"andcontacts against the lead l66. When the parts are in` the position seenVinfFig. 21, the point of the ead whenfpressed against a fixed surface,

will move into the sheath, since the prongs of thefollower bite into thefiller sections and the fillersections and follower willmove i'nto theposition .seen in Fig. l22. lThe for'- v ward movement of the end caprelatively `to the sheath will move-the parts from the position seen in-Fig..21 intothat seen inyFig.

22. When it` is desired to advance the lead after the point is worndown, the end cap is moved rearwardly and -as. thislis ixed to thefiller section 55, such section will slide' rearwardly over thecoperating pron of the follower, the rearward movement o the fol-l flower being prevented by its opposed rong biting into the other llersection. en the end cap is now pushed forwardly the -llersection 55, thefollower and the lead' will be advanced and a 4new point of leadpresented for use..

ler section In all of the embodiments of my inven- .tion herein shown, Iprovide a 'movable fillerA section to effect` the advance'of the lead.It will be seen longitudinal bore in theer section is fromri 256th@ theA shown as oblong instead of roundisoas kto position the' prongs ofthefollower, Vand in practice the grooves in the filler .sections wouldbeconstructed in all the embodiments 4ofmy invention .so as to formanfobllong 'bore, 1n cross sectlon.

In so far as I am aware, I am the rstlin the art to yconstruct a pencilwherein the .bore is formed by filler sections whlchcopera'te with afollower in such a manner that one section prevents 'rearwardfmovementof the follower while the other section effects the advance feed of thefollower, or one wherein aixed and a.' movable filler section con-A itributes. with a sheath'to form an' remeans controlled by one ofthe'sections to ceiving, longitudinal bore in which is'l'ocatedfeife'cttheadvance yfeed of' the 1 insert and lI f therefore `desire theclaims to `such features 'tov receive the interpretation tovwhich apioneer inventionfis entitled.

'When an end cap and J c ployed of the construction'seen in Figs. 11,

12 and13, it will 'be understood that, afterY an insertis'worn out, thefollower is 'fed forwardly into such position that'it'can be removedfrom the front end of the bore. A

will now`.be apparent that I have devlsed'a novel and usefulconstruction of a A vantage enumerated as desirable in the statel of itsadvantages.
